Rising Big Data

Data is the new science. Big Data holds the answers. – By Pat Gelsinger

Data is everywhere. According to the predictions, by 2025, 463 exabytes of data will be generated each day which is equal to 212,765,957 DVDs per day!

Billions of emails, millions of tweets are sent every day. Thus, every person is generating a huge amount of data which is rising exponentially.

Around 2.5 quintillion bytes of data are generated every day. This big data without information is of no use. The companies are moving towards big data technologies to gain insights and make profitable decisions.

The Big Data market will sooner reach $103B by 2023.

We all must be curious to know the big data technologies. So let us see the big data technologies embraced by the fortune companies and startups to gain business profits and many more.

Big Data Technologies

Big Data technologies are the software utility designed for analyzing, processing, and extracting information from the unstructured large data which can’t be handled with the traditional data processing software.

Companies required big data processing technologies to analyze the massive amount of real-time data. They use Big Data technologies to come up with Predictions to reduce the risk of failure.

The topmost big data technologies are:
